CIRCLean aims to be used by someone receiving a USB key from an untrusted source who wants to see the content without opening the original and potentially malicious files. The code runs on a Raspberry Pi, which means it is never required to plug the original USB key into a computer.

Ejecter is a little tool that makes it possible to unmount external devices and eject CD-ROMs without having to right-click on the device icon (either on the desktop or in Nautilus). It sits in the background and shows an icon in the system tray when one or more peripherals are connected to your PC: once clicked, a window appears with the list of the devices (volume name and device type, and much clearer than the similar thing available on Windows) and the related eject button. Being written in Vala, it is translated into C code and then compiled. This means that it's lightweight and consumes little memory, does not require a full VM like Python, and has no strange requirements to run (just GLib/GTK).

GNU usbsync is console-based utility that assists you in keeping files and entire directory trees synchronized between a portable storage volume (such as a USB flash or thumb drive) and arbitrarily many hosts. For this purpose, a special text file, usually named .usbsync, is placed in a storage volume's top-level directory to contain user-written synchronization entries.

Hanvon Tablet Linux Driver is a USB device driver for Linux kernels which primarily supports complete functionality of the Artmaster I tablets:
pen coordinates, touch/float/click detection, pressure, x and y tilt, pen button,
four simple tablet buttons (note that the first one works only together with pen
activity), and the slider button.
Some similar models are also supported by the driver.

I2C4Java is a simple demonstration of I2C-Java. It uses the Devantech USB-I2C Interface and the Microchip PICkit I2C Demoboard. The software package contains the complete Netbeans project and a compiled Jar file.

MaheshaBSD Server is a fully functional demo that never expires comes as a bootable USB image. Its purpose is to show Windows users the flexibility of running FreeBSD off a USB flash drive that works immediately as a server. The FTP server supports quotas; MaheshaBSD Server is the only pre-configured WordPress server that immediately runs everywhere. It is configurable via Webmin (remote web interface). The USB memory stick is writable; phpMyAdmin is also installed. The server can be redirected to any disk; NTFS partitions are also supported. By setting up IP forwarding on ports 21 (FTP), 22 (SSH), and 80 (HTTP), you will have the instant aibility to operate a public Internet FTP/WWW and WordPress server. Linux emulation is activated, allowing the use of many Linux tools. You can add unlimited number of accounts; however, in order to keep SFTP accounts chrooted, this needs some additional setup.

OpenSCB is a hardware and software solution for controlling servos over USB. The hardware is designed to interface with classic RC servos, AX-12/AX-18 servos, OpenServo, and more using a powerful 32-bit microcontroller with a USB port for programming and control with a PC. The schematic and layout will be available and can be customized. A graphical interface is also provided for your computer to configure, calibrate, and control the board.
